All mountains around the world have native and non-native species that are expanding their ranges quite dramatically; however, little research has been conducted towards understanding the long-term redistribution of species and the effects of global change on biodiversity.


The Afromontane Research Unit (ARU) on the University of the Free State Qwaqwa Campus – as part of the Mountain Invasion Research Network – has secured a two-year EU Horizon 2020 project under the Department of Science and Innovation, which will be looking at the mechanisms underlying the success and impact of range-expanding species on biodiversity and ecosystem functioning.

On Monday 19 July 2021, the ARU took a few of its researchers on a scenic helicopter ride to the summit of the Drakensberg for an alpine field-experiment site inspection of the Mont-aux-Sources peak, one of the highest sections of the Drakensberg range. This site has been identified for the project which the research unit will be leading on mountain research.

ARU Director, Dr Ralph Clark, said the project would explore the effects of global change, biological invasions (when species invade new geographic regions), as well as climate and land-use change. He said experiments were needed to explore the various possibilities and to test the extent to which species respond to experimental treatments. The project would therefore be conducting experiments for two years using open-top chambers – causing an increase in temperature of 3 or 4 degrees to what you find naturally – on plant species from lower down to the top of the mountain, to see how they function. “This will give us an idea of whether they will be able to survive in global warming scenarios. If temperatures get warmer, we might start seeing a lot of plants up here that we wouldn’t otherwise find here.”

Dr Clark said little is known about the long-term monitoring of species distribution and the effects of global change. Implementing the project in the Maloti-Drakensberg alpine area will therefore put the area in the global mountain research arena. The elevational gradient in the Maloti-Drakensberg Mountains provides space to explore the key processes underlying the variation in species elevation with climate change. “One of the things we don’t know much about are alpine systems. We are hoping to establish a long-term alpine research site and try to add as many studies as we can. The more science we can bring up here, the more we can know about mountain life. What happens on mountains has a lot of impact on social dynamics.

“This project is looking to see what is driving range expansion. Every mountain has its own context. In the Swiss alpine, fires are not a big factor, but fires are one of the biggest factors on our mountains. Some of our native and non-native species are therefore fire-driven, so as fire increases, you might have them spreading faster.”

UFS responds to revocation of the accreditation of the SA Doping Control Laboratory by WADA
2017-07-01

The World Anti-Doping Agency (WADA) yesterday informed the South African Doping Control Laboratory (SADoCoL) at the University of the Free State (UFS) that the WADA accreditation status of the laboratory has been revoked.

This revocation does, however, not include the analysis of blood samples for the Athlete Biological Passport for which SADoCoL has been re-accredited in August 2016 and which the laboratory will continue to perform. It also does not impact at all on the testing of urine sport samples by the South African Institute of Drug-free Sport (SAIDS), who will continue to send such samples for testing to other WADA accredited laboratories, while blood samples will be tested at SADoCoL as before.

The revocation follows a year long period of suspension in which the laboratory had to develop its analytical capabilities and instate new systems and methodologies.  “In this period the laboratory worked diligently to realize all of these requirements and according to an inspection team from the WADA Laboratory Expert Group who visited the laboratory in February 2017, much has been done and the Laboratory is in a much better state than it was before the suspension in May 2016,” says prof Marthinus van der Merwe, Director of SADoCoL.

“However, there were certain aspects of these requirements that the laboratory could not achieve within the time-frame stipulated by WADA and therefore the organisation is bound by its rules and regulations to now revoke the accreditation status of the laboratory. Since much effort and resources have been invested in the laboratory in the last two years, the management of SADoCoL together with senior leadership of the UFS decided to go ahead and finalise all development in order to re-apply for WADA accreditation,” says prof van der Merwe. 

“The UFS fully acknowledges the hard work of SADoCoL during the period of development and is committed to support the laboratory in its endeavors to re-attain its status within the very specialised and highly regulated community of world-wide doping control laboratories.  The premium goal of the laboratory is still to fully serve the sporting community of South Africa and Africa according to the WADA guidelines for anti-doping control in Sport and it is confident to attain that with the support of all role players in this field,” says Prof Witthuhn, Vice-Rector: Research at the UFS.
